Each LED is controlled by up to 20 events.
For example:
„
95 Parameters are Being Set
„ 163 Failure: Current Symmetry Supervision
„ 501 General Fault Detection
„ 1566 Thermal Overload 1 Warning Stage
„ 1571 Trip by Thermal Overload Protection 1
„ 4533 External Trip 1 is Active
„ 5616 87 Function is Blocked
„ 5621 87 Time Delay Started
„ 5641 87 Function Blocked by Harmonics
„ 5651 87 Blocked by Saturation on Phase A
„ 5817 87N Time Delay Started
Each event can either latch ("memorized"),
or not latch ("not memorized") an LED.
Latched LEDs can be reset using a key on
the front panel, a binary-signal input, or an
attached PC running WinDIGSI.
